Etched raises $700M at $21B valuation, doubling in one month

• Etched, an AI chip startup, raised $700 million led by Jane Street, a trading firm that tested the hardware before investing.
• The valuation jumped from $10.3 billion in July to $21 billion now, gaining roughly $11 billion in a single month.
• Etched designed two custom components: a low-voltage prefill chip that processes input faster, and cluster-scale memory that connects multiple chips with shared fast memory.
• Jane Street has already deployed its first production rack of Etched hardware in its own data center.
